The plug and play harness from Burger Tuning is actually undetectable once it is disconnected.
Does take that long to unplug the OEM harness-ready plugs... about 5 to 10 minutes.
If you're having an appointment with your local dealer, either for a regular oil change or for a catastrophic engine failure, just remove the PNP harness.
Of course, if you want to keep your X3 healthy for 10 years and 200 000 miles, it's not a good idea to raise to boost and try to extract more power from the whole drivetrain. There's a reason BMW is not delivering our X3s with more HP and TQ, and it's not entirely the emissions-tests' fault.
